lThe improved apparatus which forms the subject matter ofithis'fapplic'ation comprises a frame, bed, or base 20.,of any approved of the unit disclosed in this application and,

not shown. l.

The'shaft 24, carries 'cams25,' 26 and 27 provided with the necessary cam grooves for performing the functions 'hereinafter described. I 1 Erected also upon the base '20 isa bracket 28 from which 1s suspended a foraminous mold4 and upon which is imposed the valve mechanism. The foraminous mold is atf tached to the bracket 28 by securing the topmember 29 thereto by means of bolts or the like inserted through thehole 30, the'top section of the mold being rigid with 'l the bracket 28 carrying the inlet tube 31,' which is likewise rigid with the bracket 28.

The side walls of the mold are composed of members 32 as indicated -at Fig. v1 3 in elevation which members are providedwith and supported'in `any necessary meansfor attaching to the arms 'g mittin ;tl1e,1eVer 38 and is connected by means of abolt 39H with anear 40..car rie d upon the bar 41. The bar 41 is pivoted upon the upper extremities of arms v4Q.. and 43, the latter of which is provided with a cam roller 44 engagingwith and operated by the cam26. The arms 42 and 43 l. are at their lower extremity pivoted upon the base f 2O so thatfas4 the arm 43y is oscillated bythe ,camf26, .the bar 41has a movement in parallelism with the base 20.- Rotationof the cam 26 and reciprocation of the bar 41 servesto oscillate the; shaft 34 and' through the geared connection the shaft 35, which shafts carrying the mold sections tends to open.. and. 4 closeusuch molds alternately..

The bottom mold comprises a bottom 'plate :45 shown in detail atFig. 14 with the foraminouscovering removed. The .plate J.isr.carried bythe arm- 46 mounted upon the shaft 4 7 whereby when such shaft 47 is oscillated the' bottom plate 45 is moved into and out of closed position.- Tolimit the npvward movement of the plate 45 carried by A thefarm 46 and properly position such plate and .complete the moldstructure a limiting stop 48 is provided which being adjustable .abuts against the adjacentportionof the bracket 28.

To oscillate the shaft 47 offthe bottom mold section a lever 49 is carried upon said shaft and `provided with an upstanding spring controlled finger 50. Frein the finger 50 an arm 51-.pivoted thereon extends transversely across the'base and is rigidly connected to the shaft 53. The shaft/53.

journaled in the base 9.0 .is provided with the arm A54 carrying a cam roller- 55 engaging with. and operated by the cam 25. As the cam 25 rotates the shaft 53 isoscillated reciprocating link 51, andoscillating thereby lever 49. the shaft 47 raising .and lowering the bottom plate45 of the mold. The grooves of the cams 25 and 95 are such that the .bottom plate.45 is actuated to drop and the side plates to open simultaneously '.vhereby .the article within the mold .is dropped therefrom and to close simultaneously toreceive a further charge of pulp.

To control tb(` introduction of pulp a.

-valve base structure 56 is erected upon that part of the haften-t 28 overlmnging the mold and carried thereon in any nnpn-ved inane shape of the mold when completed,

Athe passage'7OQ.

5T' in holes 58. 'the valve base structure 56 is provided at its upper limit with a valve face shown at 59, especially at `Fig. 5. It is provided with duct 6() connecting with the tube 31 which extends downwardly into the mold. It is also provided centrally with an opening (3l to receive a spindle 62 land with 'an air port 63 receiving air through the tube 64.

Upon this-l iace 39 a valve member 65 is provided, journaled upon the spindle 62, u spring (36 and a tensionl nut 67 being `provided for insuring intimate-ibut. yielding contact between :the valve member 65. and the base member 5G. The valve member 65 has an opening 68 arranged to receive a. pipe 69 whichis connected by an approved flexible piping vwith a source of ulp supply not shown. :.The yvalve mem er 65 is also rovidedwitha passage 70having a port 1 positioned at times toregister with the port 63 of the base member `and outlet ports 7 2, 7 3v and l74also communicating with ner as by the bolts The fio-action lof the .valve parts and ports are shown ldi:'algru'nin,atically atfFigs.6-10

inclusive..t At 'E Fig. Q6.' port GOfand ,6 8'l are shown in registry *wherebythe pulp from the supply pipe 69 is-mtroducdby gravity through 'theI .valve structureY into the mold. The rotation .oflftheyalve .'member in the position s'hownbythefarrow first cuts off the pulp supplyby moving portsiQS and 60'oi1t of registry@ the membersfbeing i`n i`nitial position as shown in Fig. 7 V'not permitting the introduction eitherf of, air,(` I ...p'u lp..I 1 As the valve member ',65 advanes'nrther in vthe direction indicated by the arrow, the air ports y63 and 70 are brought in to communication b'ut'not into complete registry.. 'At the same timeoutlet port 7 4 is brought over the port 60 whereby.air. f r. o ml the' passage passes through the A.port Y1-and L port 74 to the passageod'nnd into thennold. The port 74 is comparatively small per; mitting the introduction of a'small volume of air. .As theyalve member 65 advances further h wever'the'port also passes over the port:',60 andA a greater volume of air is admitted. The further advance 'brings vall three ports 72,A 73 and 74`over pwt 60 whereby the maximum volume of air is p'as.edlinto fthe "mold and forces out the fluid `carriage leaving the pulpy mass adhering to the walls of the moldl It is designed to employ heated air or possibly. superheated steam whereby theiluid carriage is initially expelled andthe pulpy adhering Ynass is likewise completely or partially dried. i f v To oscillate valve member 65 thesaid member is provided with a segmental rack 75 engaging the rack 7.6 carried upon the bar 77. The bar ,77 is pivotedupon the upper extremity ofarms 78 and `79'vvhich to oscillate the cam member 65 with the required progression. As all of the cams 25, 26, and 27 are carried 4rigidly upon the same shaft 24, it is obvious that all of the said cams and the ports actuated thereby,

will operate in timed relation whereby the opening and closing of the mold is properly timed inregard to the introduction of pulp or air into the mold so that the' mold will be closed at the times the valve members` are in position shown progressively at 6-10 inclusive and to open only When the valve has been returned by the return re-- ciprocation of the bar 7 6 to theinitial posi'- tion shown a; Fig. 7. Both of the bars 41 and`77 as Well as the shaft 53 are arranged for connection with the-extremity of other shafts and bars whereby the additional units consisting of otherv molds and mold operating devices may be attached thereto and all driven from the lmaster unit disclosed in this application.

The several mold parts comprise a top 29, the sides 32 and the bottom 45 and are. covered with any approved foraminous'niaterial 81, the' oraminous material being supported upon the knife edges inter'L oled between the holes drilled throughthe several plates permitting the expulsion of the iiuid carriage through the foraminous sheets and tlirougn the holes provided in the several mold sections. lt is obvious that as the pulp suspended in the fluid. carriage is introduced into the mold a suliicient amount of fluid carriage will be expelled initially to permit the deposit of the required sheet or'pulp upon the interior of the mold Walls. When the pulp has been deposited in a suiiicient quantity and thickness the further introduction of pulp is suspended by the action of .the valve member 65, and air or other, drying fluid is introduced into the mold to complete expulsion of the fluid carriage and compact the pulp adhering to themold walls and to 1dry out or expel the remaining watery fluid remaining in the adherring pulp. In ordinary use the pulp discharge will be. in comparati rely thin sheets and the amount of the Wat-ery tluid remain- `ing in the adhering pulp will be small in quantity whereby the air, super-heated steam or other drying iiuid will quickly and readily expel such air leaving;l the pulp mass in' substa. itially a completely dried imm.
